AUTHENTICATION METHOD, AUTHENTICATION SYSTEM, IN-VEHICLE DEVICE, AND AUTHENTICATION APPARATUS
First Claim
1. An authentication method for authenticating a communication device and a portable terminal device with each other by exchanging an authentication key on connecting the communication device and the portable terminal device via communication, the method comprising:
- generating the authentication key by the communication device;
displaying on a display unit by the communication device, a two-dimensional code including the authentication key generated in the generating;
acquiring the authentication key from the two-dimensional code by reading the two-dimensional code via an imaging unit of the portable terminal device; and
transmitting the authentication key acquired in the acquiring by the portable terminal device to the communication device.

Abstract
An authentication system is configured such that: an in-vehicle device generates an authentication key, and displays on a display unit, a two-dimensional code including the generated authentication key and a URL indicating a predetermined WEB page on a network; and a portable terminal device acquires the authentication key and the URL from the two-dimensional code by reading the two-dimensional code via an imaging unit, downloads a communication program for communicating with the in-vehicle device from the WEB page indicated by the URL, and transmits the authentication key to the in-vehicle device by causing the downloaded communication program to operate.

7. An authentication device for performing user authentication based on information received from a portable terminal, the device comprising:
-
a communication unit that establishes communication connection with the portable terminal; a storage unit that stores registration information for user authentication for each portable terminal; an authenticating unit that performs a registration process of storing in the storage unit, the registration information which includes first authentication information that is unique information generated for each portable terminal and second authentication information generated for each portable terminal, and that compares the registration information stored in the storage unit with information received from the portable terminal, wherein the communication unit permits the communication connection with the portable terminal for which authentication based on the first authentication information succeeds, when the authentication based on the first authentication information succeeds, and the authenticating unit performs authentication based on the second authentication information after the communication connection is permitted. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
